1st one: GM commercial + LP Music Video
2nd one: GM commercial + LP Music Video
3rd one: I wonder.
shhh don't tell Linkinprime!!
About the only thing that would even make me remotely want to see the third one would be if they used Omega Supreme, that might make me at least want to see it once. That's assuming they didn't change everything and make him an aircraft carrier or something.
There is speculation that the scenes they are shooting around cape Canaveral are scenes for Omega Supreme or perhaps Sky lynx. Perhaps the 3rd one takes the band back to Cybertron? My guess is this will be the last TF movie so they will go all out on this one.
